Heat index

The heat index for May is estimated at a burning hot 45°C (113°F). Caution: Heat cramps along with heat exhaustion are expected. Sustained activity could lead to heatstroke.
Be aware that heat index ratings are designed for shaded locations and minor breezes. Direct exposure to sunlight could raise the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'apparent temperature', is a calculated temperature value of how hot it feels when the moisture in the air is factored in. The influence of weather is personal, with a diverse population experiencing it differently due to differences in body mass, stature, and degree of activity. Recognize that direct exposure to the sun can escalate the heat effect, potentially adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are especially crucial for babies and toddlers. Children usually face more risks than adults as their ability to sweat is less. Additionally, their larger skin surface in relation to their petite bodies and higher heat output due to their activities increases their vulnerability.
The body's self-cooling mechanism is rooted in perspiration, where evaporating sweat cools down excessive warmth. With a lot of moisture in the air, the evaporation process is not as effective, and the body does not cool down as efficiently, creating a perception of overheating. When body temperature rises due to excess heat gain beyond its removal capability, one might experience heat-related disorders.
